Energy Crisis

Over the past 200 years, there has been a dramatic shift in how we obtain energy. These changes were driven by innovations such as the steam engine, oil lamps, internal combustion engines, and large-scale electricity usage. The global transition from an agricultural economy to an industrial economy required new energy sources to provide more efficient energy input.

In terms of carbon emission reduction, China has developed around 200 GW of photovoltaic system capacity, and the electricity produced by these systems annually is equivalent to the energy output of 100 million tons of crude oil. Consuming 100 million tons of crude oil would produce approximately 350 million tons of carbon emissions, whereas producing 200 GW of photovoltaic systems generates about 10.5 million tons of carbon emissions. In other words, for every ton of carbon emissions produced in the manufacturing of photovoltaic systems, the electricity generated by these systems will reduce 33 tons of carbon emissions annually.

From an energy input-output perspective, producing a 1 kW photovoltaic system requires around 300 kWh of electricity. This 1 kW system can generate approximately 1500 kWh of electricity per year and will continue to generate power for at least 20 years. This means photovoltaic manufacturing is a typical example of exchanging "small energy" for "large energy," making it a significant industry in terms of both energy production and carbon emission reduction.
